[Also in Division H4] In an arrangement for enabling an operator to control the display on a cathode-ray tube (C.R.T.) 1, Fig. 1, associated with a digital computer 33 feeding into orthogonal deflection members 3, 4 and grid 5 via digital-to-analogue converters 29, 30, photo-electric transducers 7 . . . 10 afford outputs, from differential amplifiers 17, 18, which correspond to the manual movement of a member 11 having a grooved end, Fig. 2, the analogue outputs from the differential amplifiers being encoded into digital form for feeding into the computer which thereby modifies its programme to afford a persistent display of the path followed by member 11. A switch 25 is closed before " drawing " is required and a switch 40 is closed before erasure of a display is desired. The differential amplifiers also feed the corresponding deflexion members. The summed outputs of all transducers is fed to the computer to notify that the operator is about to intervene. A gate 39 is opened when switch 25 is closed to cause modulation of the C.R.T. beam for eliminating the effect of ambient light. A multi-colour C.R.T. may be utilized.

A digital computor interpolates points on a curve given the end points of a straight section (P 1 , P 2 ) and the end points and centre of curvature of an arc (Ps, P 4  and P M ), and is characterized that an arc with low radius of curvature is interpolated more frequently than an equal arc having a high radius of curvature using cartesian co-ordinates the formula used for interpolating a straight line having end points P A (x A , y A ) and P E (x E , y E ) is and similarly for y n . K is a constant of the computor and represents in this case the reciprocal of the number of sections into which the line will be divided. The value x E -x A  is stored and when this is zero new end values are entered. If an arc is to be interpolated (Fig.4) the formulae used are K has the same value as before but here represents the incremental angle ## made at P M  by the arc between successively interpolated points. Clearly, for two equal length arcs having high and low radii of curvature respectively there will be more interpolations in the arc having low radius of curvature. Apparatus is described employing conventional registers, multipliers (K is fixed so that multiplication can be performed by shifting), and accumulators, the x and y co-ordinates being calculated simultaneously on duplicated equipment. In the interpolation of an arc the process stops when the difference between one of the co-ordinates (which one is predetermined by choice of end points and consequent error) and the end point becomes smaller than some predetermined figure. A check is also made on whether the difference between successive co-ordinates exceeds a predetermined value, if so the operation is stopped. The binary system is preferably used throughout and the computor may be used for machine tool control.
